Most recent #CDC dataset, updated today, again omits Nowcast for the most recent four-week period, "[d]ue to low numbers of sequences being reported to CDC".
Stratus-Eleventy XFG.1.1 appears to gain share in April-May reporting, though under pressure from XFG.23.1.3 / RV and last Spring's LF.7 lineage. Cicada BA.3.2, Nimbus NB.1.8.1 / PQ, and XFZ recombinant, identified as challengers a month ago, now appear to be in retreat.
Note that, in absence of robust data from states, CDC has given up modeling historical estimates, instead giving only shares of reported sequences.
Raj's dashboard, updated end of March, showed XFG.1.1 at a quarter share, for the last half of the most recent reporting period, while Cicada grandkid RE.2 made a significant appearance.
That said, said GISAID data was dominated by paltry submissions from New York (171), Minnesota (85), Maryland (84), Nebraska (53), and Arizona (17).
